A fast-spreading flu strain in the UK is leaving more people vomiting bile, according to health experts. “Superflu” is not a recognised medical term. It is a media phrase used to describe a particularly harsh flu season driven by a mutated Influenza A (H3N2) virus. In this case, the strain belongs to subclade K and has been linked to more severe symptoms and a higher number of infections.
Experts say this is partly because the virus has changed enough to slip past immunity built from earlier vaccinations or past illness, making outbreaks harder to control. Older adults and other high-risk groups tend to be affected most.
The label is used to highlight a genetically altered H3N2 strain that reduces how well current vaccines match the virus, even though the shots still help protect against serious illness. These changes can make flu seasons arrive sooner than usual and feel more intense than people expect.
Health officials say the H3N2 variant is proving tougher than expected and is also affecting people’s appetite. Experts suggest this version of the virus may be more aggressive due to genetic changes that have made it stronger and more harmful, increasing the risk of infection. Studies indicate it can trigger more intense body aches, sudden exhaustion, and flu symptoms that appear rapidly.
Many patients have described vomiting “yellow bile” as one of the standout symptoms of their flu infection. Virologists believe this may happen because the flu is suppressing appetite more than usual, leading people to vomit when their stomachs are empty.
People experiencing symptoms such as coughing, sore throat, or a runny nose have been advised to reduce contact with vulnerable groups. This includes older adults, pregnant women, and those with existing health conditions, as they face a higher risk of serious illness.
Hospital admissions for flu in England reached 3.8 per 100,000 people in early November, up from 2.4 the previous week at the end of October, as per Mirror. Dr Simon Clarke, an infectious disease specialist at the University of Reading, told the Daily Mail: “Vomiting bile happens when someone is throwing up on an empty stomach.”
Professor Paul Hunter, an infectious disease expert at the University of East Anglia, explained that vomiting yellow bile usually occurs after repeated vomiting on an empty stomach “due to inflammation of the stomach lining.” He added that while it is often referred to as ‘stomach flu’, this symptom can appear as part of influenza. He also pointed out that yellow bile vomiting is common with stomach bugs such as norovirus and rotavirus, which are currently circulating at lower-than-usual levels for this time of year.
Additional flu symptoms include muscle pain, fever, weakness, extreme tiredness, and a dry cough. These symptoms often start suddenly and usually mean staying in bed to recover. Professor Stephen Griffin, a virology expert at the University of Leeds, told the Daily Mail that people vomiting yellow bile should focus on staying hydrated. “It’s important to drink plenty of water, even if you’re being sick, because some fluid will still be absorbed,” he said.
Health leaders raised concerns in November 2025 after a sharp rise in flu cases earlier than expected. Experts think this may be linked to the H3N2 strain mutating seven times over the summer. Data from the UK Health Security Agency (UKHSA) showed that most identified flu viruses were H3N2. Flu-related hospital admissions in England were recorded at 3.8 per 100,000 people in early November, compared with 2.4 the week before. The agency noted that this level of admissions is normally seen in December. At the time, flu activity was more than three times higher than usual for that point in the year, with children and young people most affected.
Health officials have encouraged eligible people to get their Covid and flu vaccinations to lower the risk of severe illness and hospital stays. Booster doses are available for those over 65, care home residents, frontline health and social care staff, and pregnant women. While the vaccine formula was finalised in February to allow time for manufacturing, the mutated strain emerged in June, meaning it may not fully protect against this version of the virus. Experts stress, however, that vaccination remains important to reduce the chances of serious illness and infection.
Although flu-related hospital admissions fell slightly over the Christmas period, England’s chief medical officer has warned that the NHS remains under significant strain as colder weather adds pressure. New figures released last week showed 2,676 patients were in hospital with flu, down from 3,061 the previous week. This drop was partly credited to NHS teams vaccinating more than half a million additional people compared with last year. Demand on services remains heavy, with NHS 111 handling 414,562 calls over Christmas.
Professor Meghana Pandit, NHS National Medical Director, said: “It is encouraging to see fewer people being admitted to hospital with flu, but the NHS cannot afford to relax as temperatures fall and pressures are likely to increase in the New Year. If you are eligible and have not yet had your flu jab, please come forward. It is still worthwhile.”
Health Secretary Wes Streeting added: “We are still facing serious pressures. It is more important than ever for those who qualify to get their flu vaccination and for people to use A&E only when it is truly necessary.”

The NHS has released updated guidance for people who are currently taking clonazepam, a commonly prescribed medicine that belongs to the benzodiazepine group. According to the health service, clonazepam is often used to control seizures or fits linked to epilepsy, ease involuntary muscle spasms, and help manage panic disorders. It is also prescribed in some cases for people with restless legs syndrome (RLS). NHS Inform notes that “around 1 in 10 people experience restless legs syndrome at some stage in their life.”
Explaining how the drug works, the NHS says it increases levels of gamma-aminobutyric acid (GABA), a chemical in the brain that has a calming effect. By boosting GABA, clonazepam can reduce anxiety, prevent seizures or fits, and relax tight or overactive muscles.
Clonazepam is only available on prescription and comes as tablets or a liquid. Most adults aged 18 and over can take either form. In certain cases, children as young as one month old may be prescribed clonazepam to treat epilepsy, as per NHS.
That said, there are situations where extra caution is needed. People who are due to have surgery or dental treatment, those who are pregnant, trying to conceive, or who have sleep-related conditions may be advised to stop taking the medicine. However, these are not the only groups the NHS says should be careful.
Clonazepam is not suitable for everyone. Before starting treatment, patients are advised to tell their doctor if they:
Like many medicines, clonazepam can cause side effects. Common effects, which affect more than 1 in 100 people, include disturbed sleep such as vivid dreams, feeling sleepy during the day, light-headedness, dizziness, unsteadiness, and muscle weakness.
When it comes to long-term use, the NHS warns that clonazepam can lead to withdrawal symptoms if taken for a prolonged period. Because of this risk, people who have been prescribed the drug for more than four weeks may have their dose reduced slowly when stopping treatment, rather than stopping suddenly.
The NHS also stresses that this is not a complete list of side effects. Patients are advised to read the information leaflet that comes with their medicine for full details.
Although uncommon, some people may experience serious side effects while taking clonazepam. The NHS advises contacting a doctor or calling 111 immediately if you notice:
In rare cases, clonazepam can trigger a serious allergic reaction known as anaphylaxis.

Every winter, people in Delhi prepare themselves for stinging eyes, tight chests and coughs that refuse to go away as thick smog blankets the city. Now, fresh research from Jawaharlal Nehru University (JNU) suggests there is another hidden danger in the polluted air. According to the study, Delhi’s winter smog may also be carrying antibiotic-resistant bacteria, adding to health worries in one of the most polluted cities on the planet.
The research, titled Distribution and antibiotic resistance patterns of airborne staphylococci in urban environments of Delhi, India, was published in Nature – Scientific Reports. It found disturbingly high levels of antibiotic-resistant “superbugs” in both indoor and outdoor air across the city, particularly in winter when pollution levels spike. The findings point to polluted air acting as a possible vehicle for antimicrobial resistance (AMR), which experts already consider one of the gravest global health threats.
As per Indian Express, to understand what people might be breathing in, the researchers collected air samples from a range of everyday locations across Delhi, such as:
Both indoor and outdoor air samples were taken during summer, monsoon and winter to track how bacterial levels and resistance patterns shifted with the seasons.
Across every setting, airborne bacteria levels were far above the World Health Organization’s recommended safe limit for microbial exposure. In some winter samples, bacterial counts exceeded 16,000 colony-forming units per cubic metre, which is more than 16 times higher than the WHO guideline.
What raised even greater concern was the type of bacteria detected. Many belonged to the Staphylococcus group, which includes strains linked to skin infections, pneumonia, bloodstream infections and illnesses commonly acquired in hospitals.
According to the researchers, a large share of the airborne bacteria were identified as methicillin-resistant staphylococci (MRS), meaning they do not respond to commonly prescribed antibiotics. Among these:
Notably, 14 out of 36 multidrug-resistant samples carried the mecA gene, a well-known marker that makes bacteria resistant to methicillin and related antibiotics.
The study showed that levels of airborne drug-resistant bacteria were highest in winter, while monsoon rains led to a sharp drop in outdoor contamination.
Researchers point to a few likely reasons:
On the other hand, rainfall during the monsoon appears to clear bioaerosols from the air, reducing bacterial concentrations outdoors.
Many healthy people may breathe in these bacteria without becoming sick. However, the risk is much higher for:
The researchers note that inhaling drug-resistant bacteria does not automatically lead to infection. Still, it raises the risk of infections that are harder to treat, especially if the bacteria manage to enter vulnerable parts of the body.

Researchers say consuming excessive short-form videos on social media may lead to 'brain rot' and cause cognitive decline, increase the risk of depression and worsen behavior in young children and adults.
Named as the 2024 Oxford University Word Of The Year, 'brain rot' is defined as the supposed deterioration of a person’s intellectual state due to overconsumption of low-quality online content such as TikTok videos, Instagram reels and YouTube Shorts.
Until now, brain rot was considered to be merely internet slang but now multiple studies show that the condition can, indeed, impact overall brain health and pave the way for neurodegenerative diseases.
According to a literature review published in Psychological Bulletin, a journal of the American Psychological Association, scientists found links between heavy consumption of such videos and increased symptoms of depression, anxiety, stress and loneliness.
Additionally, the September 2025 study also found that extreme intake of short form videos (SFVs) can worsen cognitive functioning and weakening emotional control as well as regulation.
Moreover, an October 2025 study from Capella University, Minneapolis which summarized 14 studies on SFVs discovered that people who regularly watch videos, ranging between 15 to 60 seconds, were prone to developing 'TikTok Brain' and suffered from low attention spans.
The review noted, "Reports from educators and parents describe teens struggling to focus in class or during prolonged tasks, behavior changes often attributed to constant stimulation from social media scrolling."
Based on these results, Keith Robert Head, a doctoral student in social work at Capella University and study author commented, "So one of the questions that would be interesting for researchers to study is: Are these ADHD diagnoses actually ADHD, or is it an impact from the continued use of short-form video?"
James Jackson, a neuropsychologist at Vanderbilt University Medical Center told NBC News, "The narrative that the only people who are worried about this are grumpy old grandpas who are yelling at you to get off their lawn or the idea that if you’re concerned about this you’re not in step with the times, I think that’s really simplistic."
He also noted that SFVs can be useful through the opportunities it creates for learning as well as community-building and social media users should seek to maintain a balance.
“There are people that engage with short-form videos in ways that are value-added, for sure. But if their engagement is pulling them away from other, more healthy opportunities, if it is isolating them from other people, if it is creating situations where they’re less and less likely to just sit around and be bored, I think that’s a problem," he said.
She further noted that it may take many years of study to determine whether cognitive changes associated with SFVs consumption are reversible and whether they can qualify as an 'addiction'
“It might be too early to claim universal doom,” Gupta said. “The research for alcohol, cigarettes and drugs took 75 years or more to develop. But I would be surprised if, in the next five to 10 years, we do not have similar signs validating the moral panic that we have around short-form videos.”
